The organisation became the first far-right group to be banned in the UK last year and its aliases Scottish Dawn and NS131 have since been proscribed.

Mr Lythgoe, 31, has also been charged with membership of a terrorist organisation, alongside Garron Helm, of Seaforth, Matthew Hankinson, of Newton-Le-Willows, Andrew Clarke, of Paddington and Michal Trubini, of Warrington.

A 22-year-old man, who cannot be named for legal reasons, has been charged with membership of National Action as well as the intention of committing acts of terrorism and threats to kill.

The defendants have been remanded in custody and are due to appear at Westminster Magistrates' Court tomorrow.

National Action was outlawed in December, with the Government citing its "virulently racist, antisemitic and homophobic" ideology.

Speaking at a security summit on Wednesday, Sue Hemming, head of the Crown Prosecution Service's (CPS) counter-terror division, said there had been an increase in arrests for terror suspects identifying themselves as from "white" ethnic groups.

There has also been a stark increase in the number of right-wing extremists referred to the Government's anti-radicalisation programme, now making up almost a third of those being monitored by Channel.
